Sukolics, Elkhart, Ind., assignor to American Metal Climax, Inc., New York, NY. Filed Aug. 3, 1971, Ser. No. 168,610 Int. Cl. E041) 2/88 U.S. Cl. 52-235 14 Claims ABSTRACT F THE DISCLOSURE There is provided an improved wall system wherein the structural portions of the vertical mullions are separate from the remaining portion of the wall. Thus, there is provided a structural mullion portion with horizontal through members wherein the interior mullion portion snaps to the structural mullion portion to lock the through horizontal members in position. The shape of the structural portion may be varied without changing the other members of the system.

The present invention relates to a new and improved wall construction, and particularly, to a new and improved framing system for exterior wall construction for a building and the like.

More specifically, the present invention is directed to a stick wall system for use on single and multi-story buildings. The term stick wall as applied to a wall system is defined as one wherein all the components thereof are factory fabricated with a horizontal member running past the vertical members and installed in long lengths. The lengths of the horizontal are limited by the stock lengths available. The factory fabricated components are shipped to the job site in lengths, or sticks. The sticks are assembled piece by piece, into a grid directly on the building. The grid is then glazed from either the inside or outside depending upon Ajob conditions. The spandrel panels may be installed along with the metal if desirable.

In accordance with the present invention, there is provided an improved stick wall system, wherein fabricanon savings are obtainable by the elimination of parts, the elimination of fasteners and the holes required for their installation, the elimination of notches in the mullions at the horizontals, and by the fabrication largely on the short pieces of the system, thereby reducing handling problems. Moreover, elimination of notches, commonly present in the mullions at the horizontals retains the full structural potential of the mullion.

Moreover, material savings have been obtained by the elimination of members and by the consolidation of several members, thereby generally resulting in a more eilicient structural member with less metal.

Although low cost is desirable in a wall system, other things must be considered. Performance is important. The framing system according to the present invention exceptionally inhibits air infiltration. Its drainage and pressure relief system functions substantially better than the required standards. The wall system provides good appearance and is versatile so as to meet the customers needs at the lowest cost.

In accordance with the present invention, the wall system also solves two other annoying problems which occur in many wall systems. One is in the entrance area. Itis desirable that a framing system or wall construction incorporates readily available entrances. Additionally, the same feature has been carried into the window area in certain embodiments of the present system. A special inswing window has been designed which does not require the buildup of material common in other systems, and accordingly the sight line does not change in the window area. An object of the present invention is the provision of a new and improved framing system for a wall construction.

Another object of the present invention is the provision of a new and improved stick Wall system.

Still another object of the present invention is the provision of a framing system for a wall construction which is economical and which combines good performance, good appearance, and versatility to meet the customers need.

Briefly, the foregoing and other objects and advantages of the present invention are accomplished by the provision of a wall system wherein the structural portions of the mullion are separate from the remaining portion of the wall. The horizontals are provided in stock lengths and run pass the mullions. The interior mullion sections snap to the structural mullion portions and lock the through horizontals into position, thereby eliminating fastenings wherever practical. l

Referring now to the drawings, and particularly to the embodiment 0f FIGSe 1-32, there is illustrated a frame 75 4 system for a building wall and the like adapted to receive thin panels. In one commercial embodiment of the system, the thickness of the horizontal is 11/2" and the system has been designated as a 11/2 stick wall system, and will receive panels 1A" to 1/2 thick.

More specifically, there is illustrated a wall construction 6G, FIG. l, including a sill member 61, a head member 62, horizontal members 63, 64 and 65, and a plurality of vertical mullions 66, 67 and 68 contained within an opening 69 of a building wall 70. The horizontal members 63, 64, 65 with the vertical mullions 66, 67, 63 form a plurality of openings which may be glazed with glass or other suitable panels 73, 74, and 76. As best illustrated in FIGS. 6 and 8 to 10, the structural portion of the mullion is separate from the remaining portion` O the wall. Considering for example, mullion 67 as typical, the mullion 67 includes a structural portion 67a here shown as a structural T mullion, but which may have any desired form such as a box, or tapered structure, and an interior mullion portion 67h.

The inner edge of the structural portion is provided with a T slot or pocket 67a` for receiving an appropriate mullion anchor. The structural portion 67a and the interior portion 67h interlock through a one way snap lock as indicated at 67d. In the common configuration of the interior mullion section 67b, there is provided a pair of opposed glazing pockets 67e, 67j of general U shape to provide for glazing in a known manner, and each containing one or more glazing or gasket grooves 67g on its inner surface adjacent its open end. As best illustrated in FIGS. 14 and l5 the panels, shown here as panels 76, may be glazed by conventional glazing gaskets 78, 79 or may be wet glazed if desired by suitable glazing gaskets 80, 81 and wet glazing 82.

The basic horizontal member is best illustrated in FIGS. 2 and 3 as members 63, 64, and 65. Considering members 64 as typical, the member 64 is of somewhat H-shape, having an upwardly opening glazing pocket 64a, provided with glazing recesses 64b along the upper inner surface of its side walls. The horizontal member 64 is also provided with a somewhat downwardly opening pocket 64o which when completed by a glass stop 84 forms a glazing pocket also having glazing recesses 64d 84a along the inner surface of the pocket legs. The glazing pockets 64a and 64d will receive the panels 74 and 76 respectively in a known manner. Where it is desired t0 provide a condensation gutter, the horizontal 64 may be modified, as shown at 64 FIG. ll, bythe addition of an external horizontally extending condensation gutter 64e dening a generally trough shape spillway S6.

The horizontal member 64 has extruded longitudinally extending splines 64f for receiving screw fasteners and the like. A drainage or pressure relief slot 85 may be provided in the horizontal member 64 opening into the upper glazing pocket 64a.

FIG. l2 illustrates a horizontal member 88, provided with a face, 88a, or glass stop removable from the outside and which, when assembled, provides a mem-ber appearance and function quite similar to members 63, 64, and 65. Advantageously, the removable face 88 provides for removal of the spandrel panel in case of damage. Suitable drainage and pressure relief slots 88h are provided on the lower edge of the removable face 88.

A typical sill assembly is illustrated in FIGS. 2 and 8. The sill or flashing member 61 is fastened to the building wall 76 in any suitable manner as with the fasteners 89. A standard horizontal is used with the sill member 61, here identied as the horizontal member 63, and which is identical to the horizontal members 64 and 65. If desired, a dry seal 92 may be used between the horizontal 63 and the sill member 61.

A typical head assembly is illustrated in FIGS. 3 and 10. The head member 62 is fastened to the building Wall 70 in any suitable manner, as by the fasteners 93. The head member 62 is of generally U-shape having a down-
